DIES FOR MAKING HQLLOW METAL WARE.

SPECIFICATION'fOrming part of Letters Patent N 0. 746,843, dated December 15, 1903. Application filed February 12 1953. Serial No. 143,118. (No model.)

To all whom it may concern:

Be it known that I, WILLIAM JONES, stamper, piercer, and tin-plate worker, a subject of the King of Great Britain, residing at 62 Oxford street, Birmingham, in the county of Warwick, England, have invented certain new and useful Improvements in Diesforj Making Hollow Metal Ware, of which the following is a specification.

This invention relates to dies for making;

hollow metal ware.

The object of this invention is in a ready" part of this specification, and in which like letters of reference indicate corresponding parts, Figure l is a view in sectional elevation showing the diiferent parts of a tapersided vessel prior to being assembled. Fig. 2 is a View in sectional-elevation exhibiting the parts of the'vessel disposed within the die and before the latter is operated to efiect curling or wiring. Fig. 3 is a view similar to Fig. 2, showing the parts of the die brought together and the curls on the vessel formed thereby. Fig. 4 is a view in sectional elevation of the vesselcompleted by the die of this invention.

the top portion being formed with an enlarged mouth portion. Figs. 6 and Z are fragmentarydetail views of the die for forming the shoulder on the vessel shown in Fig. 5. Fig. 8 is a sectional detail view of another form of vessel. Fig.. 9 is a sectional detail view of the die for forming the vessel in Fig. 8.

By the aid of the'drawings forming part hereof my improvements will hereinafter be made quite'clear.

In Fig. 1 the body part a of a metal vessel and a loose part c to form the bottom thereof are shown separately, the vessel being a taper-sided one. The body part is open at groove 6 Fig. 5 is a View in sectional elevation of a slightly-modified form of vessel in which only the bottom portion is curled,

both ends (1,2 a and is in horizontal section circular, while the part 0 (also cylindrical to fit the end a has a circular rim or flange c upon it. v This body part a, and loose bottom part and to head orfalse-wire the top edge of the said body part, the attachment of the said bottom and the heading being one operation. The tools are upper and lower ones 61 e, each in the form of the invention shown in Figs. 2 and 3 being composed of two parts 01 d e? a these parts being respectively applied to each other, so that one of them is to an extent resilient-for instance, the part d of the top toolcan slide in and out of the part 01 While the part c of the bottom tool is capable of lowering a distance independent of any-movement of the part a The bottom 1001 e, which constitutes a matrix, has a recess e formed within it of the size of the exterior of the body part a, and at the bottom of this recess is formeda cylindrical curlinggroove e The top tool (1 is a plug-tool and constitutes a swaging-die and is adapted to fit the interior of the body part a, it having formed in it at its upper end a cylindrical curling-grove 61 A Seating 6 is provided at the bottom of the recess 6 this seating providing the necessary depth in the curling- When the toolsdand eare brought together with the body part a and bottom e between them in the manner represented in Fig. 3, the lower edgea of the body part a and the rim or flange c of the bottom are curled up inwardly in the curling-groove e the said bottom being thereby made fast to the body part, while at the same time the upper edge a of the body part is headed or falsewired by itourling in the curling-groove d The reason for making the part or block 61 of the toold resilient wilhin the part d is so that the said part d shall hold the bottom 0 firmly in position upon the seating a, while the part d descends to force the body downwardly into the sinking e to a sufficient extent to make an elfective curling of the edge a and the rim or flange 0 while the reason for making the part c of the tool 6 resilient is so that there shall not be too much of the walls of IOO the body part a unsupported at any point. It will be seen from the drawings that some of the length of the body part a goes into the curling for putting in the bottom 0, While some goes into the head or false wiringformed at the upper edge of the body part, and in this particular it is to be pointed out that the making of the upper part of the lower tool e resilient proportions in an efiective manner the amount of the said body part that goes into the bottom putting-in curl and into the beading-curl, as well as provides that the said body part shall not be unsupported for any length of it, which would be liable to buckle when pressure is applied to its walls to force it bodily down into the recess 6 Fig. 2 shows the position of the tools after the body part a has been dropped into the recess 6 to rest in the curling-groove 6 the bottom 0 dropped into the said body part onto the seating 6 and the upper tool lowered into the body part, so as to be just in position to commence the putting in of the bottom 0 and the curling of the head or false wiring, no pressure on the body part a having yet been applied,although, as it will be seen from the said drawings, the

part d of the top tool holds the bottom down onto its seating with its rim or flange'in the curling-groove e The recess 6 and the plug part of the upper tool are formed so that the body part a, of the vessel is supported externally and intern-ally as much as possible when treating a taper vessel whilethebottom-putting-in curling and the heading is taking place.

The parts (1 d are made resilient in respect of each other by a spring d taking its abutment between them, as also are the parts 6 e by a spring (2 also taking its abutment between them, all parts being true in their working in respect of the axis of center of the recess e The finished metal vessel, composed of body part a and curled-in bottom 0, the said body part havinga head or false wiring at its upper edge, is shown in section by Fig. 4.

In the case of straight-sided vessels the walls of the recess 6 and the exterior surface of the plug part of the tool d would be formed parallel instead of taper.

I can provide the tools 01 and 6 so that instead of beading the upper edge of the body part a at the same time as the bottom 0 is put in they will enlarge the diameter of the said body part at the said upper end and form at that partacylindrical shoulder m, as shown in the vessel, Fig. 5, Figs. 6 and 7showing in diagram the shape of the tools for doing this,

the said tools having resilient parts operating the same as hereinbefore defined. I can also provide the tools cl and 6 so that the bottom 0 only is put in, the top edge of the body part not being beaded or false-wired, but left as represented in Fig. 1, and this by forming the tool d without the curling-groove 01 in which case the tool 6 need not have a resilient part. I can also bead or false-wire the top and bottom edges of a body part simultaneously withoutputting a bottom in it, as represented at n and o in Fig. 8, in which case the upper tool d can be made in one part, as represented in Fig. 9, there being no bottom to be held in position by the said upper tool while it is attached to the body part.

I would point out with reference to Figs. 2 and 3 that if a quarter of an inch of metal of the body part a, is to be curled up to put in the bottom and a quarter of an inch thereof toform the bead a portion of the half-inch is represented between the tools by the space 8 and another portion by the space to.

It will be seen from Fig. 8 that the body part may be parallel instead of taper by making the sinking and plug of the tools accordingly. I

Having now described myinvention, what I claim, and desire to secure by Letters Patout, is

1. The combination of a matrix composed of a fixed and a movable section, the fixed section being provided with a curling-groove, a swaging-die having its under face provided with a curling-groove, and a block carried by the swaging-die and to coact with the curling-groove in the fixed member of the matrix.

2'. The combination of a swaging-die provided on its under face with a curling-groove, a block resiliently connected therewith, and a matrix composed of a fixed and a movable part resiliently connected,the fixed part being provided with a curling-groove.

3. The combination of a hollow swagingdie provided on its under face with a curlinggroove, a block mounted to slide within the die, and a matrix comprising a fixed and a movable part resiliently connected, the upper face of the fixed part being provided with a curling-groove.

In testimony whereof I have'hereunto set my hand in presence of two subscribing witnesses.

WILLIAM JONES.
